The ear (also known as pinna or auricle) is not frequently targeted during the routine fetal anatomic assessment. However, it could provide important clues in the presence of other facial or systemic anomalies. We will review basic embryologic steps in the formation of the face that will help understand the pattern of specific ear malformations. Subsequently we will present the imaging evaluation of a group of clinical conditions with their postnatal correlations. With this exhibit we expect the reviewers to become familiar with characteristic scenarios and potential search patterns during US and fetal MRI evaluations.  

1. Embryology 2. Basic imaging assessment of the face (what normal anatomy looks like) 3. Malformations of the ears     a. Microtia/anotia            i. Definition and potential scenarios           ii. In the setting of 1st and 2nd branchial arch syndromes                        a. Hemifacial microsomia/oculo-auriculo-vertebral spectrum                        b. Treacher Collins syndrome                        c. Sometimes with ear findings: 22q11.2 deletion syndrome, Pierre Robin sequence      b. “Microtia mimickers”/Cryptotia: Epidermolysis Bullosa      c.  Malposition           i.
